The Dutch spend ten times as much on cycling as the British and they have ten times as many urban journeys/person (30%+ vs 3%+)

It figures

To make up for years of neglect, the UK should spend £50/person/year on cycling. When UK cycling infrastructure is as good as Holland’s, this can drop back to £25/year.
Just think, about this quotation from a Sky report on The British Cycling Economy.The proportion of GDP spent on public infrastructure by the UK Government has been lower than government spending in many other countries, averaging around 1.5 per cent between 2000–2004 – around half of the investment occurring by governments in Italy and France. Despite rail accounting for only six per cent of total passengers in the UK, the sector received a subsidy of around £6.5b, almost equalling road investment, which carries the majority of journeys undertaken in the country. In addition, tax revenues from transport eclipse expenditure on transport by £14b, reflecting a net flow out of the sector from receipts. Cycling’s proportion of the UK transport budget is less than one per cent, whilst in the City of London, one of the UK’s larger cycling ‘hot spots’, cycling has been apportioned 0.45 per cent of the £135m transport budget, amounting to around £600,000.54 Currently, 10,000–15,000 cyclists commute into the Capital each day, which has increased by 52 per cent since 2007, and is forecast to quadruple by 2025.55 These macro and micro conditions continue to create the ideal milieu for cycling participation to increase across social strata, with significant benefits.
